The present invention embodies sound reproducing means that are preferably mounted in a cabinet of any suitable type. In the illustrated embodiment the sound reproducing mechanism is installed in a cabinet 25, of the upright type, provided with the usual hinged cover 26, a portion only of the cabinet and cover being shown in Fig. 1. A horizontally disposed motorboard 27 is provided in the upper portion of cabinet 25, and to the underside of said board is secured, in any suitable manner, a motor 28 (Figs. 2 and 3) which, in the form shown, is an electric motor provided with power connections 29 and switch control means (not shown) of any suitable type. Preferably, motor 28 is directly attached to the lower surface of an elongated plate 30, which extends beneath a suitable opening 27a in motorboard 27, and which may be secured to the lower surface of said boardat suitable points, as by means of bolts or screws, one of the latter being shown at 31 (Figs. 3 and 4). l

In ,the preferred embodiment of the invention, the motor 28 is the only driving or power unit employed. This motor, which is in continuous operation during the actuation of the machine, is adapted to rotate the turntable and to actuate the Various automatic instrumentalities. a worm drive 32 is provided beween the motor shaft and a vertically disposed spindle 33 which projects upwardly through the motorboard and carries, above the latter, the usual turntable 34 which is continuously rotated. A suitable governor 35 (Fig. 3), that may be manually controlled by a thumb nut 36 and rod 37, is preferably provided for the driving motor. Mounted on the motorboard, at one side of the turntable 34, is a swinging tone arm 38 which carries, at the small end thereof, a gooseneck 39, and a'sound box 40 provided with the usual stylus. The large end of the tone arm communicates with an amplifying device or horn of any suitable character. It

is to be expressly understood that the invention is not limited to the type of sound reproducing instrumentalties herein illustrated.

Record tablet magazine (Figs. 1, 2, 4, and 16 to 21, inclusive) The machine of the present invention embodies novel means for holding aplurality of disk rec- As shown,

disks are supported at their centers and in parallel planes, each disk bearing against the next adjacent disk, and somewhat inclined, from the vertical, toward the turntable.

In the form shown, this record magazine comprises a plate 42, which is pivotally mounted at its lower end, on upstanding lugs 43 which are suitably secured to and project above the upper surface of the motorboard at a lpoint laterally spaced from the turntable 34. A cylindrical barrel 44, that is open at its inner end, extends through and is rigidly attached in any suitable manner in an aperture in the upper end of plate 42, with said open end substantially ush with the inner face of said plate; Slidably mounted within the barrel, and projecting through the open end thereof, is a tubular member 45 which carries at its outer end a circular spider or disk 46, which has a diameter less than that of the smallest record to be played, and which is rigidly held in position by means of an annular retaining member or thimble 47 that extends, for a short dis*- tance, within the cylindrical member 44. Member 47 also constitutes a centering member for the outer portion of a record supporting pin or rod that extends through and is rigidly secured to the outer closed end of barrel 44, as by means of the nut 49, the pin 48 being threaded and of reduced diameter at its outer end for engagement with the nut and to provide a shoulder for engagement with the closed end of the barrel. The projecting free end of pin 48 is provided with an upstanding ear 43a which is adapted to engage the lateral face of a record tablet 50 adjacent the center opening therein.

If desired, yielding means may be provided for maintaining spider 46 in engagement with the rear face of the innermost" record tablet supported on pin 48 and to insure that as the outermost record is transferred to the turntable, the remaining records will be moved along pin 48 until the record next adjacent to the one removed Will engage with ear 48a. For this purpose, pin 48 carries a coil spring 51 which has engagement at may be provided adjacent its closed end with aresilient band 52 which is fixedly attached, adjacent one of its ends, to said barrel by means Yof a suitable screw, the free end of the band being bent to form a radially projecting thumb piece 52a. At a suitable point along the length of band 52, there is rigidly attached a pin 53 which extends radially inward fromsaid band through an opening in barrel 44, the pin being of greater lengththan the thickness of said barrel. The opening in barrel 44 is of such size that the pin `can slide freely therein. The portion of the pin that projects inwardly beyond the inner surface -3 of barrel 44 is adapted to extend into a suitable opening 45a (Fig. 24) formed near the inner end of the member 45 which carries spider 46. When l the spider is in retracted position, the inner end of pin 53 extends into opening 45a and-1ocks the spider and tube 45 againstmovement under the influence of spring 51. By pressing on thumb piece 52a, pin 53 can be moved outwardly to free the spider. If desired, the inner end of member 45 may be provided with an inclined surface or -l cam portion A45h (Figs. 20 and 24), in the radial plane of opening 45a whereby pin 53 will be forced outwardly, as the spider and member 45 are moved to retracted position, and when' said last named parts are in fully retracted position, pin 53 will snap into opening 45a. By this arrange- V.-54 that extends through the wall of barrel 44, the

' rection of the turntable 34, being yieldingly re-Y latter thus being held against rotation.

Means are provided for maintaining plate 42, and the records carried thereby, in asubstantially upright position, said means being so constituted that plate 42 may be swung about its pivots toward a horizontal position when it is desired to close the cover 26 of the cabinet. As shown, one wall of the cabinet may be provided, on its inner face, with a suitable recess into which is fitted a flanged member 55 carrying a pivot pin 56 on which is mounted a latch 57 that is adapted to extend through an opening 42a formed in the lower portion of plate 42, said opening being larger than the head of latch 57. Inter-posed between the wall of the cabinetand the adjacent face of plate 42, and vpreferably on opposite sides of latch 57, are resilient members 58 (Fig. 4) which tend to move plate 42 in a clockwise direction, as viewed in Figs. 2 and 16, thereby maintaining the latter in engagement with latch 57.

When in normal operative position, plate' 42 is slightly inclined from the vertical in the ditained in this position by latch 57 and springs 58. Spider 46 may be moved by hand toward plate 42, against the tension of spring 5l, until pin 53 engages the opening 45a and locks the spider in its retracted position. A plurality of records may then be slippedover ear 48a onto the pin or rod 48. By.pressing down on thumb piece 52a, pin 53 is withdrawn from locking position, whereupon spring 51 forces spider 46 into engagement with the face of the adjacent record, the record nearest the turntable; being forced. into engagement with and yieldingly held against ear 48a. The recorcs are now held in the position illustrated inAFigs. 1, 2 and 19, between spider 46 and ear 48a, the edges of the records, adjacent the centering holes therein, resting on the upper surface of pin 48, in position to be automatically transferred into cooperative relation with the sound reproducing instrumentalities. After all of the records have been removed from the magazine, ina manner to be more fully pointed out hereinafter, and reproduced, additional records of either 10 or 12 inch diameter, for example, may be associated with the magazine, or, if it is desired to discontinue the playing of the machine and close the cabinet, latch 57 may be disengaged from plate 42, and the latter 5 may then be swung to a position above the turntable, out of the path of cover 26.

Record tablet transfer vmeans (Figs. 1, 2, 4, and

11 to 18 inclusive) The machine of the present invention embodies novel means for automatically removing record tablets in succession from the magazine, transferring the tablets to cooperative relation withV the sound reproducing instrumentalities and, after the reproduction of'each. of rthe records, removing the tablet from the turntable and depositing it in a suitable receptacle.

In the form illustrated, the transfer mechanism comprises a. record transfer member or hoop 59 which is pivotally mounted on lugs 60. 61 secured to and projecting upwardly from plate 30 intermediate the magazine and the. turntable. As will be pointedout hereafter; means are provided for swinging the hoop 59 from horizontal position, surrounding the turntable, upwardlyV to a position to engage a record supported by the magazine. The hoop 59 has an enlarged portion 59a projecting from the rear or inner side thereof, and suitable'lopenings 62 are provided. in said portion to receive horizontally disposed pivot pins 63 extending through and supported by said lugs 60, 61.

Means are associated with hoop 59 whereby records of different sizes may be'positively rey moved from the magazine and carried to the turntable. In the form shown, a block 64 (Fig. 16) isl secured by screws 65 (Fig. 11) to the lower side of the enlarged portion 59a of the transfer member. Pivotally attached to the opposite ends of block 64 and projecting upwardly through openings 66 and 67 in portion 59a, are two pairs oflaterally spaced, record engaging members or jaws 68 and 69, the pair of jaws 68v being nearer the center of the transfer hoop than jaws 69. Preferably, the members 68 and 69 have the form of bell crank levers, the lower arm of each being pivoted to block 64, and the elbows of each pair being rigidly connected by rods 70 and 71 whereby each pair of members 68 and 69 may be swung in unison, at appropriate times. about their '-pivots, to bring the upper portions of said members iiushV with the upper surface of the enlarged part 59a of the transfer member, Leaf springs 72, which are secured adjacent the middle portions thereof to block 64, extend moving va small sized record, for example, a. 10

inch record, from the magazine and transfer it to the turntable. As shown more clearlyin Fig. 13, hook 73 is pivoted at 74 to one end of an arm 75, the opposite end of said arm being pivoted at 76 to the lug 59h. A leaf spring 77, secured to lug 59h, extends underneath arm 75 and noryrnally maintains the latter parallel to the plane of hoop 59 With hook 73 projected above the said lug. If pressure is exerted on the upper end of hook 73, the latter is moved downwardly within the slot in' lug 59h, the movement being slightly resisted by leaf spring 77.

In radial alinement with hook 73, but at Va greater distance from the center of hoop 59, is a Vloool; 78, pivotally mounted on the lug 595, that is end to a pin 80 projecting from the side of hook 78. Preferably, the latter is provided with av transversely extending stop pin 78a. which is normally adapted to engage the outer end of lug 59h. A link 81, pivotally connected at its opposite ends to hooks 73 and 78 respectively, transmits the `tension of spring 79 to hook 73 and adapts the hooks for movement in unison. Inl

view of the manner in which hook 73 is mounted as previously pointed out, however, hook 73 may move independently of hook 78.

Means are provided for moving hooks 73 and 78 out of record engaging position as the hoop 59 moves to a position to deposit the record on the turntable. For this purpose, hook 78 is provided with a downwardly extending and inwardly curving arm 82 that engages the upper surface of a plate 83 (Figs. 2 and 4) as the hoop 59 moves to horizontal position. This engagement results in hooks 73 and 78 being swung about their pivots, against the tension of spring 79, the upper ends of said hooks moving radially out of record engaging position.

When the magazine is lled with record tab-r lets of small size, i. e., 10 inch tablets, it will be seen that jaws 69 and hook78 do not interfere with the functioning of jaws 68 and hook 73 when hoop 59 is swung upwardly to engage said last named elements with the upper and lower edges of the outermost recordon pin 48'. If the magazine isV filled with large sized records, i. e., l2 inch records, it is desirable to maintain jaws 68 flush with the upper surface of portion 59a of the transfer hoop in order that jaws 69 may properly engage the record to be moved to and.

from the turntable. Means are therefore pro'- vided for swinging jaws 68 about their pivots and for maintaining said jaws with their upper ends flush with the surface of portion 59a while the record hoop is in engagement with a 12 inch tablet. To this end, a shaft 84 is rotatably mounted in block 64 (Fig. 16) parallel with rod 70. The outer end ofshaft 84, which projects laterally from portion 59a, has rigidly attached thereto,

a cam 85, and xedly secured to the inner end of said shaft, is an upstanding arm 86 adapted to engage a pin 87 that is fixed to, and. projects laterally from, a cam 88 which is slidably mounted in a slot 89 extending transversely of block 64.

The upper surface of cam 88 slidably engages the lower surface of enlarged portion .59a ofthe transfer member. The outer end of cam 88 is provided with an inclined surface 88a, the extremity of which extends over and normally rests on rod 70 that connects jaws 68. The inner end of cam 88 is reduced in thickness and slidably rests on the upper surface of rod 7l. When rotary movement is imparted to shaft 84, in a manner to be described hereinafter, arm 86 acts through pin87 to slide cam 88 longitudinally, whereupon the inclined surface 88a forces rod 70 downwardly, swinging jaws 68 about their pivots against the tension of spring 72 until the upper ends of said jaws are flush with the upper surface of the enlarged part of transfer member 59.

Manually adjustable means are provided for coation with cam 85, whereby the latter is actuated during the swinging movement of the record transfer member to actuate cam 88 in the manner just described. For this purpose a shaft 90 (Fig. 3) vproject/s through the motor-board, carrying on its upper end a knurled head 90a (Fig. 1) and on the lowerend thereof a bell crank lever 91.'. The long arm of lever 91 is provided with a downwardly extending pin 92 that extends into a notch 93 formed in a bar 94 that is mounted for sliding movement in the direction of its length, immediately below the motorboard 27, the outer portion of said bar being provided, if desired, with a slot 95 (Fig. 1l) which loosely receives supporting means, including a threaded member v96 and spacer 97, attached to the motorboard, while the inner end thereof slidably rests on the inner end portion of plate 30. Fixedly attached to the upper surface of bar 94, adjacent the inner end thereof, is a cam 98 having an inclined surface 98a. and a horizontal portion 98b. Secured to the outer face of lug 61, as by means of the pivot pin' 63 (Fig. 2), is a plate 99 which carries, on its inner face, a vertcally disposed leaf spring 100 and, on its outer face, a cam 101 pivoted thereto as at 102. A pin 103 projects laterally from cam 101 into the plane of cam 98. Pivoted to the outer face of lug 61 is a dog 104, the upper end of which is engaged by the free end of spring 100 with the result that the lower end of the dog is forced into a' notch 94a, or a second notch 94h, formed in the adjacent edge of bar 94. A rigid, L-shaped arm 105 is secured to the side of the enlarged portion 59a of the transfer member in a position to 4engage the upper end of dog 104 when said transfer member is in horizontal position surrotmding the turntable, whereby the lower end of dog 104 is moved out of engagement with the adjacent notch in bar 94, against the tension of spring 10D.

The adjustment of the transfer means for handling large sized records should be made when the hoop 59 is in horizontal position. The shaft 901s rota ned by means of knurled head 90a, thereby actuating lever 91 and pin 92 in such a manner as to slide bar 94 inwardly. Pin 103 is thus moved up the inclined surface 98a onto the flat surface 98h of cam 98, thereby swinging cam 101 upwardly, about its pivot 102, into position to be engaged by cam 85 when transfer hoop 59 is swung upwardly from horizontal position. The engagement of cams 85 and 101 results in partial rotation of shaft 84, movement of cam 88, and the lowering of jaws 68 to a position flush with the upper surface of the transfer member. Bar 94 and cam 101 are locked in position during movement of the transfer hoop by engagement of the dog 104 with notch 94h, this engagement taking place as soon as L-shaped member 105 moves out of engagement with the upper end of said dog.

Hook 73 does not interfere with the functioning of hook 78, since the engagement of the face of a large sized record with said hook 73 readily forces the same to a position flush with upper surface of lug 59h, as previously pointed out.

A suitable pointer anddial may be provided for shaft 90 on the upper surface of the motorboard to facilitate adjustment of the transfer parts for handling small or large sized records.

The action of jaws 68 and hook 73, and jaws 69 and hook 78, in removing a record from the magazine, transferring it to the turntable, and removing said record from the turntable is substantially the same. When the magazine is supplied with small sized. records, the bar 64 is set with dog 104 extending into notch 94a and pin 103 resting on the upper surface of said bar, adjacent cam 98. Cam 101 is now in its lower position and will not be engaged by cam 85 to swing jaws 68. As the hoop 59 swings upwardly into engagement with theouter record, carried on pin 48, jaws 68 move into engagement with the lower edge of said record and, due to the relation of the foremost ofthe' records on their yieldable support 42 to said hoop 5 9 as' it moves about .the` pivot members 63,` and as -the jaws are then moving upwardly said'jaws move said record upwardly, relative to the remaining records in the magazine. The outer record is thus forced upwardly by jaws 68, sliding over theface of the next adjacent record, until the upper edge ofthe center hole in' said outer record is above the upper edge' of ear' 48a. As the outer record reaches this position, hook 73 engages over and yieldingly grips the upper edge of the said record to the hoop, andthe record is now carried downwardly to the turntable 34 by' the reverse movement of hoop 59. As the latter approaches the turntable, arm 82 engages plate 83 and hook 73 is -moved out of engagement with the record as the upper end of -turntable spindle 33 passes through the center hole in said record-.` 'I'he upper end of spindle 33 is preferably tapered and by its engagement with the periphery of the' center hole in the record, acts as a cam to move the record out of engagement with jaws 68, and center the same on the turntable, as hoop 59 continues its movement past the upper surface of said turntable. A

After the record, which has thus been transferred to the turntable, has been reproduced, it

is necessary'to remove the same from the turntable and to discharge it from the transfer hoop before the latter swings into engagement with the next record to be transferred to cooperative relation with the sound reproducing instrumentalities. As the record, hoop is swung upwardly, toward the magazine, jaws '68 or 69 engage the adjacent edge ofthe record which is carried upwardly by the engagement of the hoop.59 therewith. As the record passes outof engagement with the turntable spindle, the hoop has reached a position such that arm 82 is disengaged from plate 83, whereupon hook 73, or hook 18, moves \into engagement with the upper edge of the record, whereby the latter is positively swung upwardly.

Means are provided for swinging the pairs of jaws 68 and 69 to a position flush with the upper surface of the transfer member as theA latter reaches a position substantially midway of 'the` turntable and magazine, whereby the released record will slide downwardly, due to the fol-ce of gravity,across the enlarged part 59a of said 'transfer member into a suitable receptacle that is preferably positioned below the horizontal 5.5

plane of the turntable. Referring particularly to Figs. l'and 17, a shaft 1061s rotatably mounted in block 64'parallel .to rods 70 and 71. Rigidly attached to the inner end of shaft 106 is an upstanding arm 107 which 'engages a pin 108 that projects laterally from a cam 109 slidably mounted in a slot 110 formed in block 64. The lower edge of cam 109 is cut away to form two inclined surfaces 109a and 109b. Tl outer extremity of surface 10911 rests on top of rod '70 and inclined surface 109b engages the upper surface of rod 71.

The outer end of shaft 106, which projects out- I wardly from the enlarged part 59a of the transfer cured to lug 60, asby means of member 63, is a cam 116 which is adapted'to coact with linger 112 as the latter is swung upwardly by hoop 59.

When the record transfer member arrives at linger 112 has been moved into engagement with pin 114 against the tension of spring 115, due to the movement of said nnger along the surface of cam 116. Due to the contour of the surface of the latter, further movement of the hoop and linger 112 results in partial rotation ofl shaft 106 yand consequently, longitudinal movement ofcam 109. The inclined surfaces 109a and 109b of said cam swing rods and 71 downwardly until the jaws 68 and 69 are flush with the upper surface of the transfer hoop.v 'I'he reproduced record is now freed and slides downwardly along the hoop into the record receptacle.

If the machine is adjusted for playing large size records, the jaws 68 will`be held in lowered position by engagement of cam with cam 101 and the partial rotation of shaft 106 and movement of cam'109 has nov effect on rod 70. Y

Just prior to the engagement of hoop 59 with the'position illustrated in dotted lines in Fig. 2, 80

the outer record supported in the magazine, ilnger 1-12 rides over the end of cam 116 and springs 72 swing jaws 68 and .69 outwardlyto record engaging position. If the machine is adjusted for playing large size records, jaws 69 only will be returned to record engaging position -since jaws 68 will be held in lowered position by cam 88 and its associated elements.

Receptacle for played records (Figs. 1, 2, 3, 4

and 19) Means are provided for receiving the records' after they have been reproduced and removed from the turntable by the`record transfer means. Preferably the record 'receptacle is so positio `ed llo that the record tablets may move thereinto by 115 gravity, when released from the record transfer member -59. As shown more clearly in Fig. 2, the motorboard is provided with an elongated slot 117, of a length greater thanfthe diameter ofthe largest record to be played, intermediate the turntable and the magazine, and immediately below the slot 117 there is provided a receptacle 118. Preferably one wall of the cabinet forms the outer 4wall of the receptacle and the inner wall er the letter is constituted by e suitable partition 119 secured to the lower surface lof the motorboard or to the side wall of said cabinet. In order to prevent damage to the records as they move by-gravity into the receptacle, the walls of the latter are preferably' covered with soft mate- 130 rial, such as felt, indicated at 120. A hinged i closure 121 maybe `provided for removing the records fromthe receptacle 118. If desired, the inner end of plate 30 may be provided with an enlarged portion 30a (Fig. 3) having a slot there- 135 in in register with slot 117 to strengthen the motorboard adjacent the opening therein.

Driving mechanism for the record transfer means (Figs. 4 to 9 inclusive) Suitable means are provided for swinging the record transfer member through a vertical arc about pivot pins 63 to a substantially vertical position whereby alrecord is removed from the magazine, positively carried to the turntable, and

after reproduction, deposited in receptacle 118,

said driving mechanism being so constituted that the record transfer mechanism is automatically thrown into and out of operation at vthe appropriate times. In the embodiment of theinvention illustrated, this driving mechanism is thrown into operation by a reverse `movement of the stylus, which movement may be secured by providing a closed eccentric element, as a groove adjacent the center of the upper surface of the record.v It is to be expressly understood, however, that the invention is not limited to the use of an eccentric groove for moving the stylus reversely, since other means for securing this movement will readily suggest themselves to those skilled in the art.

The driving mechanism for the record transfer means comprises a disk 122, which is loosely mounted on turntable spindle 33 and which is provided, on its lower face, with a pinion 123 that is rigidly secured to, or formed integrally with, said disk. Pinion 123 meshes with a gear 124 whichlis rotatably mounted on a shaft 125 rigidly secured to a plate 126 provided adjacent one end with an opening 127 which loosely surrounds spindle 33 in the plane of the pinion 123. Preferably, plate 126 is provided with a bearing portion 126a which engages spindle 33 below the plane of pinion 123.

Integral with gear 124 or rigidly fixed thereto, is a pinion 128 which meshes with a gear 129 that is rotatably associated with plate 126 by means of a stub shaft 130, which is fixed to the center of gear 129 and which carries onits upper end, a circular disk 131 that rotatably engages the upper surface of said plate. Disk 131 overlies a circular opening formed in plate 126, and secured to shaft 130, concentric with said opening and ldisk 131 and in the plane of said plate, is a second disk 132 of less diameter than said opening,

vwhereby an annular slot 133 is formed, the outer edge of disk 132 constituting the inner wall of said slot. A stub shaft 134 extends upwardly through slot 133 and disk 131, and is provided on its upper end with an enlarged head 134a, which is secured in any suitable manner to said disk and which is provided, on the opposite sides of a slot 135 therein, with a pair of upstanding lugs 134b. The lower end of stub shaft 134 is rigidly attached to an elongated slide or plate 136 provided with a longitudinal slot 137 (Fig. 8) through which projects the turntable spindle 33. Plate 136 is adapted for reciprocating movement along the upper surface of plate 30. Fixedlysecured to the upper surface of slide 136, adjacent the end thereof diametrically opposite gear 129, is a plate 138 provided with a cam 139 having an inclined portion 139a and a transversely extending rib 139b, for a purpose to be described hereinafter.

Slidably mounted in the slot 135, provided in the enlarged head of shaft 134, is a bar 140 that is provided on its inner end with a slot 141 through which passes a pin 142 carried by a bifurcated lug 143 (Figs. 2 and 4) rigidlysecured to, or in` tegral with, the record transfer member 59. The bar 140 is provided with an elongated recess or notch 144'in its upper surface, and is retamed in position in slot 135 by means of a locking 'plate 145, removably secured to the upper face of head 134a and provided with a tongue 145a which extends between lugs 134b carried by said head. Bar

` swing the latter about its pivots. The notch 144 is of greaterlength, however, than the diameter or head 134a in order that the latter may move through a certain distance without imparting motion to bar 140 or hoop 59.

The outer end of bar 140 is provided with a longitudinal opening 146 into which loosely extends a rod 147 provided with an enlarged head 147a, on its outer end, and with a transverse pin 148 adjacent its inner end. Pin 148 extends into a slot 149 formed in the lower surface of bar 140 and limits the movement'of rod 147 relative to bar 140. Interposed between the head 147a of rod 147 and the adjacent end of bar 140, and surrounding rod 147, is alcoil spring 150 which normally maintains said rod 147 in extended position where, in certain positions of bar 140, it is adapted to engage a cam 151 xedly secured to the upper surface of plate 126.

Means are provided for connecting and disconnecting disk 122 and pinion 123 in and from driving relation/with the turntable spindle. 33.

.In the illustrated embodiment of theinvention,

this means is constituted by a clutch mechanism of the pawl and ratchet type and comprises a curved pawl 152 which is pivoted at 153 to the upper surface of disk 122', said pawl being provided with an inwardly projecting tooth 154 which is adapted to engage the teeth of a gear or ratchet wheel 155 (Fig. 4) that is fixedly secured, as by means of a suitable threaded member 156 (Fig. 8), to turntable spindle 33 above disk 122 and in the plane of tooth 154. ,A spring 157, that is secured at one end to the freefend of pawl 152 and at its opposite end to a lug 158 pressed upwardly from disk 122, tends to maintain tooth 154 in engagement with gear wheel` 155. Pivotal movement of pawl 152 is limited by means of a pin 159 which extends downwardly from the lower side of said pawl into a suitable opening or slot 160 formed in disk 122.

When tooth 154 is in engagement with the gear wheel 155, rotation of turntable spindle 33 sets in motion the train of gears 123, 124, 128 and 129. Since the pivot member for gear 129 is carried by platev 126 which is freely pivoted to the spindle 33, and since gear129 has an eccentric connection through shaft 134 to the plate 126 and to the slide 136, gear 129 acts as an eccentric to oscillate plate 126 about a shaft 33 as a pivot, and to reciprocate slide 136 for a purpose to be described hereafter. Lateral movement of slide 136 is prevented by rotatable guide members 161 which are secured to the upper surface of plate 30 that is secured to the under-side of the motorboard 27. f

The reciprocation of shaft 134 moves plate 145 along bar 140 until said plate 145 engages the outer end wall 144a of the notch 144, where Y upon said bar 140 is moved toward the turntable spindle 33. This movement of bar 140 is transmitted, through pin 142, to the'record transfer member 59, and the latter is swung upwardly about the horizontal axis constituted by pins 63 carried by lugs 60, 61.

As the record hoop moves into engagement with the outer record in the magazine, the head 147a of rod 147 engages the adjacent surface of cam 151, whereupon said rod isforced inwardly in opening. 146 and spring 150 is placed under compression. Head 134a is now in a position to begin its reverse movement inwardly toward ini- `tial position. This movement, however, is not immediately effective to produce a like movement of bar 1 40 due to the length of notch 144, but compressed spring 150 is effective to force said bar inwardly, maintaining wall 144a of said notch in engagement with plate 145, and to thus y engage the stylus from the record, and for swinginitiate the return movement of hoop 59. When the head of rod 147 moves out of engagement with cam 151 the weight of hoop 59 is eifective to return the same to ,horizontal position, but the engagement of end wall 144a with plate 145 limits the rate of movement of said hoop to that -of head 13411. -As the record hoop arrives in horizontal position, with its upper surface below the upper 'face of the turntable 34, pawl 1524s swung about its pivot 153, against the tension of spring 157, to move tooth 154 out of driving engagement with gear 155. This operation is performed by means to be described hereafter. No motion is transmitted to the gear train, plate 136, or hoop -59 during the reproduction of the record, but upon the completion thereof, pawl 152 is released, to establish the driving connection with spindle 33, and the cycle of operation just described is repeated.

Sound bom and tone arm control (Figs. 1 and 3 to 10 inclusive) Means are provided for automatically moving the sound box into operative engagement with the beginning of the record groove and, after the reproduction of the record, means are provided for elevating the sound box and swinging the same, together with the tone arm, clear of the record while the latter is removed from the turntable and a new record is placed thereon. Preferably the sound box and tone arm control mechanism is automatically thrown into operation by a particular movement of said sound bo'x, as, for example, a reverse movement of the sound box, at the end of the record groove.

In the form shown, the tone arm 38 is provided, intermediate its ends and on the lower surface thereof, with a bracket 162 (Fig. 9) which has integrally formed therewith a tubular member 163 that extends downwardly to and through an arcuate slot 164 in the motorboard 27. Slidably mounted within tubular member 163 is a vertically disposed post 165, which extends downwardly below the lower end of said tubular member and which carries on the lower end thereof an enlarged portion 166, to which is pivoted at 167 a weighted pawl 168, the pivot being so disposed that the toe of the pawl tends to hang vertically beneath the end` of the post 165. A coil spring 169 surrounds post 165 in such position that the upperend ofthe same engages the lower end of member 163 while the opposite end bears against the shoulder formed by the upper end of portion 166. Extending through an elongated slot 170 in `member 163 and pivotally connected to the upper end of post165, is a lever 171 which is pivoted, adjacent the central portion thereof as at 172, to a rigid arm 173 that is secured to the lower surface of the tone arm, adjacent bracket 164, or is formed integrally with the latter. The outer end of 'lever 171 is provided with a suitable roller 174 which has engagement with a cam 175 rigidly connected to the gooseneck 39. When it is desired to change the stylus, the sound box and gooseneck may be swung, about the usual horizontal pivot of the'latter, through an angle of approximately 180 intoengagement with a supporting arm 176 projecting laterally from the tone arm. Thereafter the sound box is returned to normal position to engage cam 175 with roller 174.

Means are provided for raising post 165 to dising said post horizontally, whereby the sound box and tone arm are moved to one side of the turntable.'` In the illustrated embodiment of the invention, said means, which preferably include mechanism for controlling the engagement and disengagement of the clutch mechanism constituted by pawl 152 and gear 155, are thrown into operation by a reverse movement of the sound box after the reproduction of the record. While in the form shown, this reverse-movement-is iin-1" v that has its opposite ends bent upwardly to form ears 179a which carry horizontally disposed pins 180. TheV latter constitute a pivot for an arm 181 that is provided at one end with downwardly extending ears 181a which pivotally engage pins 180, and at its opposite, end, with a transversely and horizontally disposed plate 182 which is bent upwardly through 90 degrees as at 183, and is bent a second time through 90 degrees, in a reverse direction to form a horizontally disposed portion 184.

The arm 181 is adapted for engagement with plate 138 and cam 139 and, in order to reduce the friction between these elements, said arm is preferably provided with an opening into which is loosely fitted a ball 185 (Fig. 8) that is retained .in place by a plate 186 secured to the upper surface of said arm, the ball having rolling engagement with plate 138. A suitable anti-friction def vice, such as a roller .187 (Fig. 3) having its upper periphery extending Very slightly above plate 30, 'may be provided for the reciprocating slide 136, immediately below ball 185, to reduce the fricf tion between plate 30 and slide 136 at this point. A bell crank lever, comprising arms 188 and 189, is pivoted at its 'elbow to a stub shaft 190 that projects upwardly from and is carried by arm 181. Preferably, a spring 188 may be connected at one end to arm 188 and at its opposite end tc arm 181 to resist pivotal movement of the bell crank lever about pivot 190. In one position the arm 188 is-adapted to engage the free end of pawl 152 whereby the latter is swung about its pivot to move tooth 154 out of driving engagement with gear 155. The other arm 189 of the bell crank lever overlies arm 181, and is provided at its free end with a large, horizontally and transversely disposed portion 191, which bears on plate 182 and has formed, on its upper surface immedi- -ately below post 165, a series of ratchet teeth that stop 195 which limits movement of arms 181 and 189 toward spindle 33, thereby insuring that arm 188 will be stopped in a position for engagement with pawl 152.

A notch 196, having a vdepth l slightly less than the thickness of arm 181, is

formed in plate 194 adjacent stop 195 to provide for the lowering of arm 188 into the plane of pawl 152. A second stop 197 is formed at the outer end of plate 194 to limit the outward movement of arms 181 and 189, and that portion of the edge of said plate intermediate stop 197 and notch 196 is preferably inclined downwardly toward saidstop to facilitate outward movement of said arm.

During the reproduction of the record, the tone arm and post 165 swing inwardly due to the driving force exerted on the stylus by the spiral sound groove. Due to the inclination of the series of teeth 192, the pawl 168 rides freely over the same. Upon the completion of the reproduction, the stylus moves into the eccentric groove and thereby receives a reverse movement, which is transmitted to post 165 and pawl 168. The latter now engages one of the teeth 192 thereby swinging bell crank lever 188, 189 about its pivot and moving the arm 188 out of engagement with pawl 152. Spring 157 now forces tooth 154 into driving engagement with gear 155, starting the gear train which reciprocates slide 136 and moves cam 139 into engagement with ball 185. The movement of the latter up the inclined surface 139e of cam 139, swings arm 181 upwardly, about pivots 180, out of notch 196 in plate 194. This upward movement is transmitted, through arm 189, to post 165, lever 171 and cam 175, to the sound box 40, thereby raising the stylus out of engagement with the recordv disk. Ball 185 now rests against the ridge portion 1391) of the cam, and the continued outward movement of slide 136 acts through these elements. to swing arms 181 and 189 -outwardly into engagement with stop 197, the sound box and tone arm being carried along by engagement of the post 165 with the vertical shoulder at the inner end of portion 191 o1' arm 189. Pawl 168 is so formed that when plate 191 is raised to lift the sound box from the record the toe of the pawl is out of engagement with the teeth 192 so that movement of plate 191 to the left, (Fig. 9) as will be described more fully hereafter, is not effective to carry the post 165 and tone arm to the left with it.

The parts are now in position to permit removal of the played record and the transfer of the next record to playing position. The slide 136 continues its outward movement to perform this transfer operation and, since arms 181 and 189 are held against further swinging, the ridge 13912 of cam 139 is forced underneath the ballA 185 and continues its' outward movement for a predetermined distance. As previously pointed out, slide 136 has its movement reversed simultaneously with the initiation of the movement of the new record toward the turntable, and as the record is deposited on the latter ridge `1391) has returned to a position'to reengage ball 185 (Fig. 8),' and swing arms 181, 189 inwardly.

Preferably, means are provided which, in the form shown,. are manually adjustable, for returning the sound box and tone arm to starting position for either small or large size records. For this purpose, the portion 184 of arm 181 has pivoted thereto, as at 198, a curved and horizon tally disposed arm 199 whichv is adapted for en.- gagement, intermediate its ends, with member 166 carried by post 165. Arm 199 is also adapted for engagement, adjacent its free end, with 'a stop pin 200 that extends downwardly from one arm 201a of a bell crank lever that is pivoted at 202 to the lower face of a plate 203 which preferably attached to the under surface of motorboard 27. A spring 204, which is secured atone end to arm 199 and at its opposite end to portion 1484,

tends to move said arm in a clockwise direction into engagement with pin 200.

The other arm 201b of the lever carried by plate 203 is pivoted to one end of a rod 205 which has its opposite end connected to the short arm of bell crank lever 91 (Fig. 3) which is adapted for adjustment by means of the knurled head 90a of shaft 90.

A bar 206 (Fig. 10) is slidably secured to the lower face of plate 203 as by means of flat-headed screws 207 which extend loosely through slots 208 in said bar. Pivotally secured to the latter,

adjacent one end thereof, is a lever 209 which is yieldingly held in a predetermined position by means of a coil spring 210 that is fixed at one endto bar 206 and at its opposite end to one end of said lever 209. The bar 206 is preferably adjustable with pin 200 and for this purpose said pin has pivotal engagement with said bar.

During the playing of a record, arm 199 yieldingly engages stop pin 200 (Figs. 2 and 9) but when arms 181 and 189 are swung outwardly, in a manner described above, arm 199 is carried outwardly by arm 181 and is disengaged from pin 200, the action of spring 204 being limited by engagement of said arm 199 with the upstanding portion 19la of plate 191. Member 166 carried by post 165 is moved into engagement with arm 199, after said member wipes past the free end of lever 209, due to the movement of arms 181 and 189. As the two latter arms are swung inwardly by engagement of ball 185 and cam 139, arm 199 is carried inwardly and acts through member 166 on post 165 to move the sound box inwardly. During the inward swinging movement of arms 181 and 189 the post 165 is maintained in raised position and the toe of pawl 168 is out of engagement with teeth 192 whereby plate 191 and teeth 192 are not effective directly to swing the tone arm inwardly. Arm 199 next engages pin 200 which has been adjusted for a large or small size record, whereupon said arm is no longer effective to move post 165 as it moves about its pivot 198 in an anticloekwise direction due to the continuing in ward movement of arm 181. The arm 199 is thus disengaged from post 165 as the sound box reaches starting position, but at this time the enlarged portion 166 of post 165 has been moved into engagement with lever 209 andthe tone arm is held by said lever in starting position. The movement of arms 181 and 189 continues untli they drop into notch 196, whereupon the weight of the'sound box lowers the stylus into engagement with the rotating record. This movement is sufficiently retarded, however, to prevent damage to the record. Just prior to the engagement. of the stylus with the record, arm

188 moves into engagement with pawl 152, there- I by moving tooth 154 out of driving engagement with gear 155. As the arm 181 drops into notch 196, plate 191 carried by said arm is lowered and this permits post 165 and the enlarged head 166 carried thereby to be moved downwardly under the force of spring 169. The shoulder formed by the upper end of head 166 drops below the end of lever' 209, thus freeing the tone arm for inward movement over a record tablet.

It will be understood that when it is desired to play large size records shaft 90 is moved in such a direction that pin 200 is swung away from the turntable, whereby arm 199 will be moved out of driving 'engagement with the tone arm more quickly than when said pin is adjusted for small size records. ThisV adjustment of pin 200 also results in movement ofi lever 209 to a suitable position for yieldingly and momentarily retaining the sound box at 'the starting position.

Operato11l1f all the records have been re` m. lecte'd records are then placed on the projecting end of pin 48 and the Aoperator presses thumb piece 52ste release spider 46, whereupon the latter is forced outwardly, against the adjacent surface of the inner record, by means of spring 51. The records are now yieldingly held in the position illustrated clearly in Figs. 1 and 19. An additional record may also be placed on the turntable if desired and the sound boxemoved inwardly `until the stylus is in engagement with the beginning of the groove of the record.

It will be assumed that the `record placed on the turntable, andY those mounted on pin 48, are of the small size, or of 10 inch diameter. The knurled head 90a is adjusted accordingly, and bar 94 is thereby moved outwardly so that pin 103 is clear of c am 98, and-'cam 101 occupies the position illustrated in Fig. 8, where it will not be engaged by cam 85 as the transfer member 59 is swung about its pivots. Simultaneously with the movement of bar 94; rod 205 swings .the bell crank lever 20111, 201b to properly adjust pin 200 and lever 209.

The motor switch (not shown) which may be of any suitable or well known type, is then closed` to .supply power to the electriclmotor 28, and the.

sound box is moved by hand to such a position that the needle or stylus is brought into engagement with the beginning of the sound groeve of the record. This latter is not essential, however, since the tone arm control mechanism will automatically move the stylus into proper posi- "tion if it is not so moved by hand. Y

As the reproduction of the record is completed,

the stylus moves'into the eccentric groove adjacent the center of the record, and the reverse movement thus imparted to the tone arm causes pawl 168 to engage ratchet 192 and swing bell crank lever 188, 189 about its pivot 190. As larm 188 moves out of engagement with the free end I through post 165, to the sound-box whereby the stylus is lifted out of engagement with the record. Continued movement of slide 136 swings the arms .181 and 189 about the vertical pivot 178, and due4 to the engagement oftheXshoulderon portion 191 of arm 189 with the post 165, the soundbor. and tone arm are swung clear of the record. In

this swinging movement the portion 166 of post 165 readily moves past the free end of lever 209 and comes into engagement with arm 189. When arms 181 and 189 engage the stop 197, further movementof slide 136 forces the ball 185 over the raised portion 1391) of cam 139 (Fig. 8).

No movement of the record transfer means VYoccurs until the tone arm is clear'of the record, this delayed action being insured by means o f the notch 144 formed in bar^140 which permits considerable'movement of members 134a and 145 before the latter engages the endwall 144a of said,notch. When this engagement occurs, the

\tone arm and sound box are clear the'record and movement is now imparted to rec rd transfer member 59 to swing the same upwardly about. the pivots 63. As-hoop 59 swings upwardly it engages'the lower face of the record on the'turntable, and jaws 68 engage the inner or lower edge of the record..l Immediately thereafter, as arm 82 cears the plate 83, hook 73 isl forced i-nto en` gagement with the outer or upper edge of then 85- record by means of spring 79. The record is thus lifted from the turntable. As the record hoop continues its upward movement finger 112 moves along the surface of cam 116 and into engagement with stop pin 114 of the` arm 111. when 0*,-

-jaws are flushv with the upper surface of plate 59a. At thisA time the record transfermember 59 has assumed substantially the position illus-z trated in dotted lines in Fig. 2, hereupon the force of gravity slides the recor Idownwardly m5' through slot -117 into the receptacle 118. Rod continues its forward motion andthe record transfer'member 59 is swung into engagement with the outer record supported by the magazine. Plate 42 is swung about its pivots, lm against the tension of springs 58 by this engagement, and simultaneously, the jaws 68 move under the lower edge of the outer record since, as the hoop assumes an upright position, `finger 112 snaps over the upper end I.of cam116 to re- 1w' lease shaft 106 and permit the springs 72 to return the jawsy 68 andv 69 to their normal position projecting above the upper surface of plate 59a. Due tothe axis of the. record transfer member 59 being positioned at a distance from the pivotal axis of the magazine, the jaws 68 have an upward movement4 relative to the records fmounted in the magazine. This upward movement of jaws 68 carries the outer` record upwardly until the center hole in the same clears 1% the upper edge of the toe 48a of rod 48 and the spring 51 frees the record from the rod 48. The pressure of thehoop acts on hook 73 to snap the same over the upper edge of the record. The

'record is 0W disengaged from pin 4s ,and held between jaws 68 and hook 73, whereupon hoop '59 begins its return movement toward the turntable, since at this time plate is moving .away from the 'wall 144a of notch 144. Spring ,150, which has been placed under compression by 13B the engagement of rod 147 with cam 151, acts on the bar 140 to move the lsame in a reverse direction and the hoop 59 isv therefore moved reversely toward the turntable, finally resuming a horizontal position as is clearly illustrated in Fig. 2, the record being deposited on the turntable as the hoop passes by the upper surface of the same.

Slide -136 at this time has returned toward 'its starting-position a sufficient .distance to bring 145 the raised portion 1391) of cam 139 into engagement with the ball 185,'and the arms 181 and 189 are swung inwardly toward the turntable spindle 33. The spring-pressed arm 199 now engages the lower end of post and the tone arm *150 turntable spindle.

is moved inwardly toward the outer edge of the record or toward starting position. This movement continues until arm 199 engagesthe downwardly extending pin 200, whereupon no further movement is imparted to the post 165 and the tone arm. The needle or stylus is now in raised position above the starting point. The inertia of the tone arm'and sound box is not effective to move the sound box past starting position due to the engagement of the lower end of post 165 with the spring-held le`ver 209; Arms 181 and 189 continue their movement, however, toward the turntable spindle until they engage stop 195 formed on plate 194;- The continued movement of slide 136 forces ball 185 over the cam 139 and as said ball passes down the inclined face of said cam, arms 181 and 189 move by'gravity into the notch 196 formed in plate 194. Substantially simultaneously with this .movement, arm 188 engages the free end of pawl 152, and due to the movement of the latter, tooth 154 is forced out of driving engagement with gear 155 and the downward movement of arms 181 and 189 permits spring 169 to force post 165 downwardly, thereby acting through lever 171 to disengage roller 174 from cam 175 and permit the sound box to be gently lowered into engagement with the rotating record.

The record is now reproduced and when 'the' stylus enters the eccentric groove at the end of the record the automatic movements are again initiated in the manner described above. The cycle of operationsjs repeated until all of the records in the magazine have been played. If the record transfer member 59 returns to its horizontal position in the plane of the turntable 34 without depositing a record on said turntable, the tone arm is swung inwardly to starting position in the normal manner and the sound box is lowered but no further movement. of the automatic mechanism takes place since no force is present to carry the stylus inwardly toward the If it is desired at any time to discontinue the playing of a record it is only necessary to raise the sound box by hand and move it in toward the turntable spindle and then return'it a slight distance to simulate the movement given to the stylus by the eccentric groove in the record. The automatic mechanism will be thrown 1nto operation to swing thetone arm clear of the turntable, to'discharge the record thereon into the receptacle 118, and transfer another record to playing position.

If it is desired to supply the magazine with larg size or 12 inch records, theknurled head 90a is rotated to bring pointer opposite the indication corresponding to the large size records. This movement of the pointer and knurled head a results in the rotation of shaft 90 which acts through pin 104 to slide the bar 94 inwardly toward lug 61. This adjustment of the machine should be made when the hoop is in a horizontal position, in the plane of the turntable, since at this time member 105 holds the toe of dog 104 out of engagement with the notch 94a in bar 94. The movement of the bar inwardly causes pin`l03 to ride up on the cam 98 and assume a position on the horizontal portion 98h of said cam, with the cam 101 in a position to be engaged by cam 85. The rotation of shaft 90 also acts throughA spondence with the pin 200. As the record trans' fer member 59 moves upwardly to remove 1a record from the magazine, cam 85 engages the cam 101 and shaft 84 is partially rotated. Rotation of shaft 84, which takes place in the direction of the arrow in Fig. 17, acts through arm 86 and pin 87 to move cam 88 longitudinally. This movement of cam 88 causes the cam surface 88a to engage shaft 70 and swing the jaws 68 downwardly about their pivots until the upper ends of said jaws are ush with the upper surface of plate 59a. The jaws 68 therefore do not interfere with the engagement of jaws 69 with the the upper edge of the record and the same is posito the turntable.

When it is desired to discontinue the playing ltively carried by the record transfer member 59 of the machine and close the cabinet, latch 57 may be raised by hand and the magazine structure may then be rotated to a position over the turntable. In this position the magazine does not interfere with the closing of the cover 26.

It will be perceived that Aa sound reproducing machine has been provided which includes novel magazine means for supporting a plurality of records in position to be moved into cooperative engagement with the sound reproducing instrumentalities'and that no adjustment of the magf'l azine structure is required to adapt the saa'n'eto` y T.'f The machine '115 r'ecords of different diameters. embodies novel mechanism for disengaging the record tablets from the magazine, the record transfer member having an upward movement substantially parallel to the face of the record tablet for this purpose, and for positively carrying the records to playing position on the turntable. The transfer mechanism also embodies means for positively moving the record, after the .same has been reproduced, from the turntable and discharging the same by gravity into a suitable receptacle that is preferably located below the plane of the motorboard. The record engaging means are so constituted that the same do not interfere with the sliding movement ofthe record tablet from the transfer hoop into the record receptacle. Means are also provided for raising the sound reproducing instrumentalities, for swinging the same clear of the record -and subsequently returning the same to starting position on the record. Manual means are provided for so adjusting the mechanism that the sound reproducing instrumentalities may be moved to different starting positions depending on the size of the records it is desired to play. Novel means are provided for driving theV record. transfer mechanism, and the tone arm control mechanism, from the power means employed for rotating the turntable, said means being so constructed that the operationsrare positively performed in the proper sequence. Only one driving element or motor need be employed. The device is extremely compact and pleasing inv appearance.
